Automount drives on Linux
Mar 20, 2024 am 11:30 AM
If you are using a Linux operating system and want the system to automatically mount the drive on boot, you can do this by adding the device's unique identifier (UID) and mount point path to the fstab configuration file. fstab is a file system table file located in the /etc directory. It contains information about the file systems that need to be mounted when the system starts. By editing the fstab file, you can ensure that the required drives are loaded correctly every time the system starts, thus ensuring stable system operation. Automatically mounting drivers can be conveniently used in a variety of situations. For example, I plan to back up my system to an external storage device. To achieve automation, ensure that the device remains connected to the system, even at startup. Likewise, many applications will directly
